Stage One Astronomy

Introduction

Look up into a dark cloudless sky and be amazed.
Amateur Astronomy can often appear to the beginner, to be very confusing, technical and testing subject. However, with a little knowledge, there is a tremendous amount of enjoyment that you will create, from exploring the night sky. No expense is required to enjoy the hobby of amateur astronomy you will be amazed how much of the night sky you will see with your eyes alone. Many people make their observation without any access to dedicated equipment. This Website aims to assist people with no knowledge of astronomy, through to an advanced level.

Go outside on a dark, cloudless night. Preferably away from any bright sources of artificial light and look up at the sky. What do you see? The Moon perhaps, stars, some twinkling, some faint. Maybe, one of them is a planet, but which one. What is the difference between a star and a planet? A brief flash of light streaks across the sky – a meteor! What is it? Where did it originate? Towards the west, a point of light moves slowly across the sky before fading in the east, an artificial satellite, perhaps the International Space Station. What about unpredictable phenomena such as bright comets and aurora?

We have selected a range of articles to supply you with useful information,

hints and tips, together with some observational challenges for all 

levels of experience.

The British Astronomical Association (BAA) is the UK’s premier organisation for the amateur observer; We have created this site to give you the skills to get out in the evening and become one with the night sky.

These pages are an evolving resource, so please check back from time to time, to see what is new

The solar system consists of our star, the Sun, and everything bound to it by gravity, which includes the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune, dwarf planets such as Pluto, dozens of moons and millions of asteroids, comets and meteoroids.

Constellations

Ever since people first wandered the Earth, great significance has been given to the celestial objects seen in the sky. Throughout human history and across many different cultures, names and mythical stories have been attributed to the star patterns in the night sky, thus giving birth to what we know as constellations.
